General Information (Physical Facilities, Number of Laboratories and Classrooms etc.)

In our department, there are 6 laboratories in total, including 4 research laboratories which are Patch-Clamp and Evoked Potential Laboratory, Electromagnetic Field and Biomechanics Laboratory, Animal Behavior Laboratory and Electrobiophysics Laboratory, 1 Student Laboratory and 1 Experimental Animal Laboratory. Our laboratories are used for scientific research and project studies, as well as for educational activities. In our laboratories;

  • Using electrobiophysical measurement system; electromyography (EMG), electroencephalography (EEG), electrooculography (EOG), electrocardiography (ECG), nerve stimulation and conduction velocity measurements, muscle contractions, arterial and venous pressures can be recorded in humans and experimental animals.
  • Tensile and compression performances of bone can be measured with the bone biomechanical test device.
  • With the muscle biomechanical test device, parameters related to muscle dynamics can be measured.
  • With the soft tissue biomechanical test device, the tensile performance of tissues such as tendon and skin can be recorded.
  • Bioelectrical events at single cell level can be examined with the microelectrode recording system.
  • With the patch-clamp system, ion channel currents are recorded and analyzed.
  • With the magnetic field setup, the effects of the electric and magnetic fields, that we are constantly exposed to, on the biological system can be investigated.
  • By measuring body impedance with electrical bioimpedance (impedance cardiography or TEB: Thoracic Electrical Bioimpedance) system, hemodynamic parameters of the cardiovascular system can be determined.
